SPECIFICATION forming part of Letters Patent No, 63 3,428, dated September 19, 1899. Application filed February 23,1898. Serial No. 671,839. No modeli lie it known that I, RANDOLPH i. CORY, residing at St. Louis, in the State of Iiiissouri, have invented a new and useful improvement in Choke Attachments for Guns, of which the following is a specification.

My invention is an improvement in choke attachments for guns, and particularly in the class illustrated hy my former patent, No. 555,432, dated February 25, inihgnnd the present invention seeks to provide means whereby the fastening strain in securing, the choke attachment to the guubarrel is exerted in lines parallel with the axis of the barrel and choke-secti0n; and the invention consists in the novel constructions, coml ina tions, and arrangements of parts, as will he hereinafter described, and pointed out in the claims.

In the drawings, Figure l is a side view. Fig. 2 is an .lGW, and Fig. 3 is a perspective v'e showing a portion of the harrel and the choke-section detached.

The gun may he singleharreled, as shown, or may be doubicdnnizied, if desired. Upon the barrel near its muzzle i provide the catches or projections arranged approximately diametrically opposite each other in position for engagementhy the latch on the choke-section.

The choke is shown as a short-barrel length or section adapted at its end for connection with the muzzle of the un barrel 'lhis choke-section i; may be suitably formed to choke the gun and has pivoted to its opposite sides, near its end which connects wih the gun-barrel, the links 0, Whichare pivoted at C to the choke 15 by means of p ns or screws passed throng :lots l) in the lint: 0, such links havingset-screws arninged to engage the said screws, so that 1e links may he adjusted for th p -us of tiring a tight fit when the latclgpresently 'crihed is engaged with the catches or 1 :tlons A on 'thegun-lmrrel.

A itionol' the parts the links ti lie approximately parallel t0 the direction of length of the choke-section, so that. the strain by which the choke-section is secured in place is exerted on straight lines and in line with the said choke-section,

thus avoiding any twisting strains thereon and securing it tirmly and steadily in position.

The latch E is pivoted at E a the end of its yoke ii to the swinging ends of the links This latch has a yoke E which connects the swinging ends of the links J and bends around the harrcl and is provided with the seatslfi, which engage the catches or projee tions A on the guirbarrel. 'lhisonahles the links to extend in latched positi n along the opposite sides of and parallel to the gun-ban rel and choke-section tor the purposes and reasons hereinhefore' described. The E are arranged on crank projections, which, together with the yolze, form what may he termed a double-hell cranlelever, by which the choke-section is drawn tightly to its place and held. by the movenieht of the cranks E slighly beyond their pivots when in the latched position. Ahai nrojectionll extends from the middle ot the yoke and may be pressed down in securing the latch or lifted in releasing it, the handle he Q t at id for convenience in or ation.

in applying the choke attachment to guns the sense-rows will he found convenient in the first instance in securing a-propertitand subsequently from time to time to take up wear as it may occur.

The links are otlset at i, so that their swinging ends may pass over the projections A and properly receive the ends of the yoke E,carrying. the cranks for engagement with the parts A.

It is manifest the parts A may be integral with the gun-harrel or he sep ti t and so cured thereto in any dt d miznne.

it is manifest the chotceattachment can be rilled andolid halls shot through the same as through a rilic.

it is manifest that the. choke att; can be tempered so that :i-tiy-sizeri so he shot from it without injnrying cho IQ.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

'1. An attachable choice for guns compria ing thecholce-scctior, the links pivoted therc-- to 51nd presided with latch devices and the aehinent 0t ca:

ion

set-screws for adjusting the said links at their 7 pivotal connection wit-h the choke-section substantially as described.

2. An attachable choke for guns compris ingthe choke-section, the links pivoted theretoand having at their swinging ends olise'u portions, and the latch comprising a yoke fitting at its ends within said offset portions substantially as described.

The herein-dcscribezi improvement consisbing of the gun -barrel having opposite catches or projections, the choke-section, the links pivotally and adjusmbly connected at one end with the choke-section and having at thciro yositeenclsollscu mrtions zirran 'ed 1 to swing over thecatches on the gun-barrel and the latch havingn bent yoke pivoted at its ends Within the offset portions of the links and having the cranks provided with seats to engage the catches or projections on the gunbarrel, and the handle projecting fromjhc middle of the yoke substantially (le scribed.
